How can I configure a USB midi controller keyboard (Alesis Q61) to control both Midi Designer Pro AND a Hauptwerk organ on a Macbook Pro at the same time? I am able to connect the keyboard directly to my computer and play the HW organ keys. I am also able to connect the keyboard directly to my iPad and control an MD button from a Sustain pedal. I need to connect to both at the same time. In the layout image, the small down and up buttons are supercontrols to the DOWN and UP stepper buttons. They respond to CC 2-64 and 3-64 from 2 different keyboards and advance the DOWN or UP stepper. The button settings image shows what I have configured for one of the small buttons.
I want to be able to trigger the stepper up or down in MD from hardware switches connected to the keyboards Sustain input while playing the organ keys in the computer.
